Childhood Epilepsy with Occipital Paroxysm: Classification, Atypical Evolution and Long-Term Prognosis in 35 Patients

Area of Science:

• Neurology
• Pediatric Neurology

Background:

• Childhood epilepsy with occipital paroxysms (CEOP) encompasses various syndromes with distinct clinical and EEG features.
• Understanding atypical presentations is crucial for accurate diagnosis and management of CEOP.

Purpose of the Study:

• To analyze the clinical and EEG characteristics of CEOP, focusing on atypical ictal symptoms, evolution, and outcomes.
• To evaluate the current classification of CEOP and its implications for patient management.

Main Methods:

• Retrospective study of 35 patients diagnosed with CEOP.
• Classification of patients into Panayiotopoulos syndrome, Gastaut syndrome, and mixed types.
• Detailed analysis of ictal symptoms, EEG findings, and patient evolution.

Main Results:

• Nine patients (25%) with mixed-type CEOP exhibited atypical ictal manifestations including vomiting, visual symptoms, eye deviation, and headaches.
• Five patients demonstrated atypical evolutionary patterns.
• The study suggests that strict delineation into early-onset or late-onset CEOP may be inappropriate due to mixed clinical findings across ages.

Conclusions:

• CEOP can present with significant atypical symptoms and evolutionary patterns, particularly in mixed types.
• A flexible approach to CEOP classification, considering mixed clinical findings irrespective of age, is recommended.
• Further investigation into the reasons behind atypical CEOP presentations and age-related evolution is warranted.
